ABSTRACT Due to the special requirements of the transit bus operator function, the environment can be a very difficult place to work, especially for large males and small females. This work addresses the design of bus operator workstations such that they fit or accommodate people from the 5th percentile female to the 95th percentile male per SAL J833. The motivation of the work presented is to reduce injuries and workers' compensation claims. While attempting to maintain the amount of adjustment at a minimum to contain costs, adjustment was included in many components like the instrument panels, seat and steering wheel. The controls were grouped in the instrument panels by their function, such that those used often are grouped together and those dealing with passenger pick-up and delivery are placed in a right-hand instrument panel. Ingress / egress of the operator, often necessary to assist passengers such as those using wheelchairs, is facilitated through movement of the components like the seat and steering column. A jury evaluation of over one hundred subjects was conducted in a static mockup. The jury evaluation showed that the workstation accommodates the above population range and provides the range of component location adjustment required for a population ranging from the small female to the large male. Also, a scientific approach using the neutral seating reference point (NSRP) was used to determine ranges of design variables. Next, the program JACKS was used to validate the design specifications. In addition, a study was conducted to determine which seat would be the "best" to use in terms of an objective vibration comparison. Finally, the design specifications were implemented into a prototype consisting of a retrofitted ~ 973 GMC bus. Twenty-four bus operators were used in evaluating the prototype by driving the vehicle through various maneuvers. From the joint measurements, component measurements, and operator comments, it was found that the workstation was suitable. The small female operators felt some decrease in comfort during the driving session; however, it is felt this was due to the seat. The medium and large operators did not feel a measurable decrease in comfort.
